Question:

Given the structures of products A, B and C in the following reactions:
(i) CH3CH2Br + KCN → A
A + LiAlH4 → B
B + HNO2 → C
(ii) CH3COOH + NH3 → Δ A
A + NaOH + Br2 → B
B + CHCl3 + Alc.KOH → C

Solution:

(i) CH3CH2Br + KCN → CH3CH2CN
CH3CH2CN + LiAlH4 → CH3CH2CH2NH2
CH3CH2CH2NH2 + HNO2 → CH3CH2CH2OH
(ii) CH3COOH + NH3 → CH3CONH2
CH3CONH2 + NaOH + Br2 → CH3NH2
CH3NH2 + CHCl3 + Alc.KOH → CH3NC
